You could use FlowViewer with the flow-tools underlying collector option if you're collecting v5 netflow. This will permit you to keep long-term graphs (ala MRTG - Last 24 hours, Last 7 days, etc.) for each AS peer with 5-minute granularity You can also graph specified time intervals at much smaller time-bucket sizes. FlowViewer has an IPFIX (e.g., v9, FNF, etc.) underlying collector also; SiLK. However, last I checked, SiLK is not collecting AS information. https://sourceforge.net/projects/flowviewer Regards, Joe From: "Peter Kranz" <pkranz@unwiredltd.com> To: <nanog@nanog.org> Date: 04/10/2015 11:26 AM Subject: Open source alternatives to UNINETT Stager for visual netflow peering analysis Sent by: "NANOG" <nanog-bounces@nanog.org> We've really enjoyed the open source Stager platform for netflow analysis, however the code has not seen updates in recent years. Looking for alternative open source netflow analysis platforms with a web interface. There are quite a few netflow tools around these days, and we are looking for something that performs the steps needed to showing us traffic volumes to particular AS#'s and their downstream customers for peering analysis decisions. I can get coarse answers from nfdump, but would like something more elegant for the NOC to use.
